Eine methode zurüberführung von acylakylidentriphenyl-phosphoranen in thioacylalkylidentriphenylphosphorane
摘要:
Starting from acylalkylidenetriphenylphosphoranes 1 the corresponding thioacylalkylidenetriphenylphosphoranes 4. have been synthesized via the triflates 3 and converted into the salts 8. Some spectroscopic data of the new compounds are discussed.

While thermolysis of thiocarbonyl-stabilised phosphonium ylides generally results in extrusion of Ph(3)PS to give alkynes, those with a P=CH function instead undergo a novel P to S transfer of a phenyl group to give (Z)-configured 1-phosphino-2-sulfenylalkenes of interest as bidentate ligands.
